1. The Influence of the Adenosine A1-receptor on Tubuloglomerular Feedback and Renin Release
Sammanfattning : The kidneys play a vital role in the maintenance of extracellular fluid and electrolyte balance and blood pressure. Adenosine, acting through the adenosine A1-receptor (A1R), and nitric oxide have been implicated in several of the regulatory mechanisms in the kidney. LÄS MER
2. Unraveling the importance of solid and adsorbed phase mercury speciation for methylmercury formation, evasion and bioaccumulation
Sammanfattning : Monomethylmercury, MeHg, is formed under anoxic conditions in waters, sediments and soils and then bioaccumulated and biomagnified in aquatic food webs, negatively effecting both human and wildlife health. It is generally accepted that precipitation of mercury, Hg, and adsorption of Hg to e.g. LÄS MER
3. Machining and fatigue induced damage in bolted composite laminates
Sammanfattning : The effects of hole machining defects on strength andfatigue life of carbon/epoxy laminates with open holes andpin-loaded holes subjected to static and fatigue loading havebeen investigated. Traditional drilling techniques causingvarying extent of damage and a novel method causing nodetectable damage were employed to machine the holes. LÄS MER
4. Shadows of Cavernous Shades: Charting the Chiaroscuro of Realistic Computing
Sammanfattning : During the early 1990s, a novel style of programming often referred to as component-oriented programming quickly grew popular as the state-of-the-art in graphical user interface and client/server development on Windows-based personal computers, largely in competition with object-oriented programming, a partly similar, partly different programming paradigm, with which component-orientation is often compared, combined, and confused. Also during the 1990s, the world-wide web spread its arachnoid gossamer over the globe with deep-ranging ramifications for software component technology. LÄS MER
5. What is Wrong with Extinction?
Sammanfattning : The aim of this investigation is to answer the question of why it is prima facie morally wrong to cause or contribute to the extinction of species. The first potential answer investigated in the book is that other species are instrumentally valuable for human beings. LÄS MER
